Airtac SGCJ200-250 Adjustable Cylinder SGCJ250X350-50S
The AirTAC Airtac SGCJ200-250 Adjustable Cylinder SGCJ250X350-50S is a genuine double acting, adjustable stroke ISO 15552 (orig. ISO 6431) tie-rod air cylinder with a Ø250mm bore and 350mm stroke, G1 air ports and adjustable end cushioning. Its large-bore tie-rod build delivers high thrust and drops into standardized ISO 15552 mounting on heavy automation.

About the Airtac SGCJ200-250 Adjustable Cylinder SGCJ250X350-50S
Delivering massive thrust with a 24543 N push at 0.5 MPa, this large-bore ISO 15552 tie-rod cylinder handles about 14726 N of safe working load, which translates to lifting roughly 1251 kg vertically with a 2:1 margin. Four steel tie rods clamp the aluminum barrel to the covers for high structural rigidity, and the G1 air port feeds the 50 mm piston rod. Because this is a 250 mm bore, TPU seals are not available; standard NBR packings handle the -20 to +70 C range, with a Viton H option for 0-150 C heat.
The -50 code means an external adjuster can shorten the extend stroke on-site by up to 50 mm, giving a usable forward travel of 300 to 350 mm without swapping the cylinder. The retract end remains fixed. Fitted with a piston magnet (-S), it supports CMSG, DMSG and EMSG switches for position sensing. It is dimensionally interchangeable per the ISO 15552 mounting interface, dropping into existing large-bore fixtures.

Where the Airtac SGCJ200-250 Adjustable Cylinder SGCJ250X350-50S Is Used
Heavy Pallet Forming
Exerts 34360 N at 0.7 MPa to compress bulky goods, using the 50 mm adjuster to set the exact final pallet height on-site.
Large Gate Actuation
Shifts heavy industrial valves with a 23562 N pull at 0.5 MPa, relying on the 60 mm adjustable air cushions for soft end-of-travel deceleration.
Stamping Press Feed
Pushes thick materials into a press with up to 5006 kgf max force, using the G1 port for rapid high-volume air delivery.
Is the Airtac SGCJ200-250 Adjustable Cylinder SGCJ250X350-50S the Right Cylinder?
When sizing this 250 mm bore unit, stepping down to a 200 mm bore drops the 0.5 MPa push force to 15708 N, while this model provides 24543 N. It is the top standard size, so exceeding its capacity requires custom multi-cylinder mechanics. The 50 mm adjustable window is ideal for sharing one spare cylinder across several stroke variants or fine-tuning the end position on-site. Mounting options include FA, LB, TC, FTC, TCM1 and TCM2 brackets. The -S magnet enables electronic or reed sensing. For any stroke at or above 500 mm, always use external guide rails to prevent side-load damage, though this 350 mm unit is compact enough for basic self-support.
Quick checklist
- ✓ Required force at your working pressure
- ✓ Stroke and mounting space
- ✓ Port/thread type (PT / G / NPT)
- ✓ Magnet (-S) for sensors?
- ✓ Long-stroke side load — support the rod end
Installation & Maintenance Notes
- check Use clean air filtered to 40µm or finer.
- check Keep within 0.15 – 1.0 MPa operating pressure.
- check Avoid side load; support long strokes at the rod end.
- check Set cushions to minimum, then release gradually.
- check Use correct mounting accessory (LB/FA/FB/CA/CB/CR/TC).
- check Installation by qualified personnel per AirTAC docs.
Airtac SGCJ200-250 Adjustable Cylinder SGCJ250X350-50S FAQ
At 0.5 MPa it provides 24543 N push and 23562 N pull. At 0.7 MPa it provides 34360 N push and 32986 N pull. The theoretical maximum is 5006 kgf at 1.0 MPa. The air port is G1, the rod is 50 mm with an M42x2.0 thread, and it has 60 mm adjustable cushions.
The nominal stroke is 350 mm, which is the maximum forward travel. The external adjuster lets you shorten the extend stroke on-site by up to 50 mm, yielding a usable range of 300 to 350 mm. The retract end is fixed. This mechanism only sets the end position; it does not lock the load on air loss, so use an external rod lock for holding.
